专题04 阅读理解之说明文 （一） （22-23八年级下·武汉汉阳区·期中）Malaria (疟疾) has been a big problem for humans since ancient times. Usually, people get malaria when infected mosquitoes (被感染的蚊子) bite them. Many people have died from the disease. Luckily, Chinese scientist Tu Youyou found an effective drug (药) called qinghaosu (青蒿素). In 1969, Tu became the director of a national project to develop the medicine to treat malaria. They studied books about classical Chinese medicine. After reading more than 2,000 old remedies (药方), Tu and her team collected over 600 plants and listed almost 380 possible remedies for malaria. One remedy, which is 1,600 years old, uses sweet wormwood (青蒿) as a treatment. Tu found it worked and tried to extract (提取) the qinghaosu from it to make a drug. The extraction failed at first, so Tu returned to the classical books again and finally found a way. She used a low - temperature method to extract the qinghaosu and finally succeeded in 1972. After her team showed that qinghaosu could treat malaria in mice and monkeys, Tu and two of her coworkers decided to test the drug on themselves before trying it on human patients. It turned out that qinghaosu was safe, and all patients in the test got better. Gradually, qinghaosu became the first - line treatment for malaria recommended (推荐) by the World Health Organization (WHO), saving millions of lives around the world. In 2015, when Tu was given the Nobel Prize in physiology or medicine, she refused to take all of the praise. Instead, she praised her coworkers and Chinese traditional medicine.
